Sometimes placements are tricky. Different crags throw up shallow cracks, off-width cracks, old peg scars, all of which are hard to protect with conventional nuts. Peenuts offer an excellent alternative, they have a tapered profile allowing them to fit where a regular wire won\'t seat. Extra Features: Hot forged to maximise stength and weight. We\'ve colour coded them in a size for size way with wallnuts i.e. Silver size 3 Wallnut =  Silver size 5 Peenut. Label on upside down so you can confirm the size more easily when the units are hanging on your harness. Elephants like them.           Product Weight Strength Colour Catalogue No             Size 1 9.4g 4kn Red A1511A     Size 2 9.7g 5kn Grey A1512A     Size 3 10.1g 5kn Purple A1513A     Size 4 16g 8kn Green A1514A     Size 5 18g 8kn Silver A1515A     Peenut set No. 1-5 63.2g NA NA A1511/15A
